Abstract: An angiographic injector system and a method of controllably delivering medical fluid to a patient from an angiographic injector system are disclosed. A multiple processor control system is used to actively control the injection process and to monitor sensed functions of the system. The multiple processors provide dual redundancy safety circuits for critical control functions such as syringe motor drive speed and current. A motor/servo-amplifier nested control function is also disclosed. A unique method and apparatus are disclosed for establishing injection parameter default values just prior to an injection procedure that are based on physiological values of the patient to be treated. The injector system uses an interactive display panel that presents sequenced set-up screens to the user and which enables the user to select injection procedures, parameters and other modes of operation directly through the interactive panel.

Abstract: A system and method is provided including a fluid communications network that sends priming and waste fluid to a waste bag, obviating the presence of open fluid containers in an operating room or catheter lab. The fluid communications network is constructed and arranged to allow nearly automated priming and bubble removal, thereby reducing the possibility of operator caused errors in set-up and reducing the time required for set-up. The fluid communications network is useable for attachment to a balloon catheter for inflation thereof. In order to provide greater control and automation of the inflation of the balloon catheter, a conversion kit is provided that can be used to convert an existing automatic injector into an injector useable for automatically controlling the small amount of injection fluid typically associated with balloon catheters.

Abstract: A catheter enabling a reduced puncture hole size into the skin and blood vessel is disclosed. In one embodiment, the catheter has an elongate body having an expandable sheath extending at least a portion of its length. A pressure constraining sheath is positioned to surround the expandable sheath, at a selected region to prevent expansion of the inner sheath at the region of the constraining sheath. In one preferred use, the constraining sheath is positioned at the puncture hole. During use, the catheter increases in cross-section by an expandable sheath expanding from a first diameter to a second diameter. However, the outer sheath does not expand, maintaining a small diameter at the puncture site.

Abstract: An apparatus and method of use or treatment are disclosed for creating intrauterine adhesions resulting in amenorrhea. In particular, the apparatus relates to an easily deployed intrauterine implant that readily and consistently reduces or eliminates abnormal intrauterine bleeding. In addition, the apparatus is also used as a uterine marker device for visualizing endometrial tissue thickness and potential changes. The method of the present invention serves as a supplement to or a replacement for conventional hysterectomy or ablation/resection procedures used to treat menorrhagia.

Abstract: A pneumatic control device includes a housing, a pressure control member secured to the housing, a first fluid-conduit member, and a first sensor. The pressure control member is constructed and arranged to selectively change a fluid pressure within the control member. The first fluid-conduit member is in fluid-flow communication with the pressure control member. The first sensor is in fluid-flow communication with the first fluid-conduit member. The sensor is constructed and arranged to generate a control signal based upon the fluid pressure within the control member. In preferred systems, the pneumatic controller is useful for producing a variable control signal to control a rate of fluid dispersement to a patient in an angiographic system.

Abstract: Retaining device on a single-port feeding tube connector for patient feeding set to prevent unintentional disconnect of the feeding solution supply tube from the feeding tube.
